Default Paint Sprayer Problem!!!

I found a Graco STX paint sprayer on Craigslist for $50, it looked new, was clean and worked great so I bought it! I thought I SCORED big time but I was oh so wrong. Got it home and after about 5 minutes of spraying the fuse on the circuit board blows! No big deal right, I replaced the fuse and 5 minutes later it blows again! I checked for shorts and anything that looked like it may be an issue but found nothing and no matter how many fuses I replace it still blows them! Like I said I've checked the obvious and I'm not taking it to a Graco service center because I'll spend as much there as I would buying a new one so what else can I check that could possibly be blowing fuses?

Try thinning the paint, make sure you sift out any particles with a good filter, and do not use an extension cord.

Does it trip when you run just plain water through it?

Could be a worn out motor.

See if the motor has serviceable brushes, maybe they are worn out.

OP,
Is there any other appliance or device on the same circuit that is high demand and is cycling on at the same time the sprayer is operating? Could the breaker just be weak? Have you tried it on a different circuit?

Yeah, I've tried everything! The only thing that some what works is as soon as it builds up pressure I shut it off and spray until it looses pressure and then power it back up, build pressure and repeat the process. I'm not a professional painter so it works good enough for my little projects it just gets annoying sometimes, lol!
